Technical Field

The invention relates to the field of daily supplies, in particular to a drinking water cup.

Background

At present, a double-layer metal water cup is commonly used, and high vacuum exists between double-layer metals. One type of vacuum cup gives the following parameters: the room temperature is 20 plus or minus 2 ℃, and the boiling water temperature is 95 ℃; the temperature is measured to be more than 87 ℃ within 1 hour, and the temperature is measured to be more than 71 ℃ within 6 hours, which shows that the heat preservation effect of the existing double-layer vacuum cup is good.

However, the temperature of water suitable for drinking is close to the body temperature of a human body, the body temperature of the human body is about 36 ℃, and the temperature of water capable of being drunk smoothly is 30-50 ℃. At a relatively high temperature, small-mouth drinking is required (the water is neutralized by the liquid in the oral cavity to be below 44 ℃, and the water has a relatively hot feeling above 44 ℃). In summer, because the room temperature is high, the human body is easy to sweat and lose moisture near the body temperature, and a large amount of water is needed to be supplemented; the boiled water is beneficial to sterilization and reduces the breeding of bacteria, but the heat preservation time of the vacuum cup is too long, so that the temperature of the drinking water can not be adequately provided. The existing vacuum cup is more suitable for being used in winter. Is not suitable for summer.

There is now a technique: paraffin is filled between the double-layer metals, and the paraffin melts to absorb heat and the paraffin cools to release heat to achieve a good heat preservation effect. The main problems that exist are: (1) to realize better heat preservation, the paraffin layer should be isolated, namely, a three-layer structure is required, paraffin is contained between the two inner layers, and vacuum is arranged between the two outer layers, so that the structure is more complex; (2) paraffin is not pure and has no fixed melting point; (3) one report reports that the heat of solution of paraffin is 224KJ/Kg at 70-80 ℃; the water capacity of the water cup is approximately 400 milliliters (approximately equal to 400 g), and assuming that the water temperature is reduced from 95 ℃ to 70 ℃, namely, the temperature is reduced by 25 ℃, the heat required to be released is 400 × 25 × 4.18/224=0.18Kg, namely, the volume of the water cup needs to be increased by 180 grams additionally, which is approximately equal to half of the volume of the water cup, so that the water cup is heavy; (4) after the paraffin is melted, the temperature of the water and the temperature of the paraffin are both approximately 70-80 ℃, so that the temperature is still higher (is not suitable for drinking), and if the cup body is of a three-layer structure, the water temperature is kept at the high temperature for a long time; if the cup body is of a double-layer structure, paraffin is used as a heat transfer medium to connect hot water inside the cup body with outside air before and after the paraffin is melted, so that the heat is quickly dissipated, and the heat preservation effect cannot be achieved; (5) if the structure (composition) of the paraffin is adjusted, namely the content of the small molecular weight is increased to reach the freezing point near the room temperature, on one hand, the weight of the water cup is increased; on the other hand, after a cup of water is drunk, as the paraffin also stores energy (liquid), the quick temperature reduction effect of reuse disappears (the heat preservation effect is enhanced on the contrary), namely the repeatability is poor.

Disclosure of Invention

In summer, the heat dissipation can be rapidly realized, but in a temperature section suitable for drinking, a better heat preservation effect is needed.

The invention adopts the technical scheme that the purpose of the invention is realized by: the utility model provides a water cup, includes bowl cover and cup, and the cup is sealed bilayer structure, and bilayer structure's inlayer is called the cup inlayer, and bilayer structure's skin is called the cup skin, characterized by: water vapor is arranged between the two layers.

And (4) proposing: at 100 ℃, the pressure of the water vapor between the two layers is 1 standard atmosphere. Further improvement: the outer side of the inner layer of the cup body is a layer of metal grid, and a gap of 0.1-0.2mm is formed between the inner side of the grid and the outer side of the inner layer of the cup body. The improvement is that: the cup body is inverted, a circular ring-shaped partition plate is arranged between the outer side of the inner layer of the cup body and the inner side of the outer layer of the cup body, so that a container is formed between the outer side of the inner layer of the cup body and the inner side of the outer layer of the cup body, the partition plate is the bottom of the container, liquid water is filled in the container, the outer side of the bottom of the inner layer of the cup body is submerged by the liquid water by 1-2cm, and the depth of the part of the liquid water between; the distance between the bottom of the outer side of the inner layer of the cup body and the bottom of the inner side of the outer layer of the cup body is 3-4 cm; the partition board is provided with a hole for sealing and connecting the pipeline, and the pipeline is communicated with the upper part and the lower part of the partition board.

The invention has the beneficial effects that:

(1) the water vapor is in a gas form of water (H2O), is clean and environment-friendly, and can not bring health risks if leakage caused by damage of the cup body occurs; the water vapor sealed between the two layers is heated by the water temperature inside the cup body, so that bacteria and viruses are not possible to exist;

(2) at 100 deg.C, the saturated pressure of water vapor is 10⁵Pa (close to one standard atmosphere); the saturated pressure of water vapor is 0.7 x 10 at 90 degrees centigrade⁵Pa; at 80 degrees centigrade, the saturated pressure of water vapor is 0.5 x 10⁵Pa; at 70 degrees centigrade, the saturated pressure of water vapor is 0.32 x 10⁵Pa; at 60 degrees centigrade, the saturated pressure of water vapor is 0.20 x 10⁵Pa; at 50 degrees centigrade, the saturated pressure of water vapor is 0.12 x 10⁵Pa; the saturated pressure of water vapor was 0.075 x 10 at 40 degrees centigrade⁵Pa; the saturated pressure of water vapor was 0.043 x 10 at 30 degrees centigrade⁵Pa; from these parameters, it can be seen that as the temperature of the water in the inner layer of the cup body decreases, the air pressure between the two layers decreases rapidly (due to condensation of part of the water vapor into water), and the movement velocity of the gas molecules decreases (due to the temperature dependence of the movement velocity of the gas molecules), which is one of the ways of heat dissipation (convection), therefore, as the water temperature decreases, the air pressure of the water vapor between the two layers decreases, and the heat preservation effect is achievedThe effect is gradually enhanced (the convection heat dissipation mode is gradually weakened);

(3) compared with a paraffin wax heat preservation mode, the invention has the advantages that the water vapor content is low, and the additional mass can be ignored;

(4) the water quantity is increased, the water cup is inverted, the water container arranged at the bottom of the water cup can accelerate heat dissipation (the effect of filling water into the water cup is better) due to the principle that hot water floats upwards and cold water sinks, and after the water temperature is proper, the water container is placed right again, the water temperature is reduced, the air pressure between the two layers is also reduced rapidly, and heat preservation is facilitated;

(5) is easy to be repeatedly used.

And (4) proposing: at 100 ℃, the pressure of the water vapor between the two layers is 1 standard atmosphere (to prolong the heat preservation time in spring and autumn, the pressure can be reduced to other pressure, such as 0.5 atmosphere).

Further improvement: one deck metal mesh 6 is hugged closely in the outside of cup inlayer 1 (wave and make moisture spray in the outside of cup inlayer 1, because there is 0.1-0.2 mm's gap between net inboard and the 1 outside of cup inlayer, and the surface tension effect of liquid, liquid can depend on in the gap between the inlayer cup outside and net (do not drip), make moisture fully contact the 1 outside of cup inlayer, make outside moisture be heated and volatilize into gas easily (gaseous state water, thereby take away the heat), gas (water) move the inboard of cup skin 2, through the air in the contact heat dissipation to the cup skin 2 outside.
